Katherine and Joe Jackson are being interviewed by the LAPD and LA County Coroner’s investigators, RadarOnline.com has learned exclusively.

“Two coroners investigators are at the home of Joe and Katherine Jackson, along with members of the LAPD,” Lt. Fred Corral of the Los Angeles County Coroner’s Office told RadarOnline.com Monday afternoon.

“They are expected to be there for a few hours. We went out there to confirm everything we collected, and answer any questions they have. This is done in all cases. It’s a routine follow-up that our office conducts.”

An autopsy was performed on Michael by the Coroner’s Office on June 26, with the results deferred pending further tests. Corral says that toxicology results typically take eight to 10 weeks, but “We are going to try and get them back in this case in six to eight weeks. The tests are conducted in our office. The Jackson family has been very cooperative with us.”
